Thank you very much for the reply.
I switched to ConTeXt standalone and now it is working.

Best,
Michael


This works:

\usemodule[simplefonts]
\definefontfeature[hebrew][default][script=hebr,ccmp=yes]
\setmainfont[Ezra SIL SR][features=hebrew]
\setupdirections[bidi=on]
\starttext
בְרֵאשִ֖ית בָרָ֣א אֱלֹהִ֑ים אֵ֥ת הַשָמַ֖יִם וְאֵ֥ת הָאָֽרֶץ
\stoptext


BTW what is the \definefontfamily syntax that would work with
\setupbodyfont in the new post-simplefonts era?

Best,
Michael

PS Just FYI here is what I had been working with:

What platform are you using, what version of Ezra SIL SR (likely 2.51,
> but worth asking)?


I am using linux (ubuntu 14.04)

fonts-sil-ezra package
Package fonts-sil-ezra:
i   2.51-8         trusty          500
(I presume this means version 2.51.)

I am using the current ppa:reviczky/context-daily version of context:

ConTeXt  ver: 2014.03.25 16:58 MKIV beta  fmt: 2014.5.1  int:
english/english

Here is the error message that I was receiving (when I include
"script=hebr"):

<+ /usr/share/texmf/tex/context/third/simplefonts/t-simplefonts.lua>)error:
/usr/share/texmf/tex/context/base/font-otn.lua:805: attempt to call upvalue

As to the by-the-way, see message 56606 
<http://www.mail-archive.com/ntg-context%40ntg.nl/msg56606.html> in the 
list archive. This is not the post-simplefonts solution, but the 
pre-simplefonts solution. It does allow much better control over all of 
the fonts that make up the typeface (using ConTeXt terminology).

The example shows what to do to set a document that is primarily Hebrew 
(or other RtL script). If you want to mix directions, bidi may be a 
better choice than the setupalign of the example. If you use bidi, I 
suggest \setupdirections[bidi=on,method=two]. I find that without method 
two, there is a problem with punctuation. In particular, the comma in

    some text {\heb *????*}, some more text

gets set before, not after, the hebrew text.

If you set only some Hebrew/Aramaic/Arabic, and especially if you do not 
need font variants (bold, italic, ...) you might prefer to define a 
single font. I have used:

    \definefontfeature [aramaic]
                        [default]
                        [ccmp=yes,
                         script=hebr]
    \definefont        [aramaic]%% KeterYG from
    http://culmus.sourceforge.net/taamim/
                        [KeterYG-Medium.ttf*aramaic sa 1]
    \setupdirections   [bidi=on=,method=two]
    \starttext
    English {\aramaic ???? ???} English again.
    \stoptext

I do note as well that there is a problem in the example in the linked 
message. It looks to me like the order of components is beth/shva/dagesh 
(for the first letter (and beth/qamatz/dagesh for the first of the 
second word), which ConTeXt sets incorrectly.  When the order is changed 
to beth/dagesh/qamatz-or-shva, they are set correctly. If you use vim, 
the command ga will show the decomposition of the character components.

Here are the two versions of that letter, first in the order that sets 
correctly:

    ???

and then in the order that does not:

    ???
